With analyzing the environmental status of law enforcement and job demands, the environmental protection mobile enforcement system was developed based on Android platform and SOA architecture. Using this system, the ability of environmental law enforcement supervision and management was improved, and various environmental administrative law enforcement issues were solved under the limited environmental management resource. Taking Shanxi Province as an example, the environmental protection mobile enforcement system was designed and developed in term of data integration, sharing resources, standardize management and function expansion. This system can been connected to the environmental Internet of Things system which was proved practical.
